study to evaluate and compare the efficacy and safety of azm and aml combined and alone in mild-to-moderate essential hypertensive subjects

Conditions: Essential Hypertension

Summary: this is an 8-week, randomized, double-blind phase 3, multicentre study to determine the optimal dose of azm and aml in combination therapy and to compare efficacy and tolerability of the combined therapy to each of the monotherapy in essential hypertensive subjects who are not adequately controlled on azm and aml monotherapy.
